Parker JM Clipper® Seal
Whitepapers On Whiteboard
Welcome to our next installment of ESP’s “Not All Seals Are Created Equal.” Today we are going to talk about a seal that’s been around for a long time, but in some cases may be one of the best-kept secrets in the utilization of rotary shaft seal applications. And that is the Parker JM Clipper® seal.
Standard Oil Seals
What makes the JM Clipper® seal a little unique is that when we think of radial shaft seals, oil seals, we think of a metal can on the OD with a rubber element that has been molded to it that acts as the sealing element. Sometimes it has a spring to help provide the necessary pressure on the sealing lip – the necessary load – to allow it to function properly.
Parker JM Clipper® Seal
With the Clipper® seal you have a composite OD that is integral with and molded with, the elastomeric sealant component – can also have a spring to it for added load. Many of the same characteristics as what the traditional metal seal would be. So very robust seal and it provides a lot of rather unique benefits and features from the normal oil seal. Let’s take a look at a few of them.
- As mentioned, the composite OD already provides a gasket type seal. So, it exactly does perform as a sealing element as opposed to just metal-on-metal and it does not require any type of plates or secondary components to keep it in place.
- It’s composite so it’s not going to rust or corrode – creating contamination issues.
- It is a one-piece molded construction for the entire size range, which makes it a little bit more robust than the normal mechanical crimping or in some cases adhesive gluing of the rubber to the outer can.
- It eliminates a lot of the problems of thermal expansion when you have extreme heat, extreme cold, and metal-on-metal – sometimes losing some of that friction fit that is necessary for the oil seal to stay in place and perform.
- It is much easier to install and is very user-friendly.
- It is also able to be designed for split models as well.
The Parker JM Clipper® seal has been around for a long time. It’s utilized in a lot of different industries, a lot of different applications, and one that wanted you to be aware of.
